Adjustable steel louvers are 1000 mm wide x 1000 mm high. They are supplied complete with a

galvanized steel mesh, blades and framing. They are made from the same material, finish and color as wall panels. Fixed steel louvers are available in 1000 mm wide x 1000 mm high, 1000 mm wide x 1500 mm high and 1500 mm wide x 1000 mm high.

5.7 Gravity Ventilators

Gravity flow ridge ventilators are 3000 mm long with a throat opening of 300 mm or 600 mm. They are installed as either individual units or as

continuous (i.e. joined) units. The outer skin of the ventilators is pre-painted Zincalume steel that matches the color of roof panels. The ventilators are supplied complete with bird screens. A damp-er system to close the throat opening is optional on 300 mm throat ventilators.

For export shipments, ventilators are shipped knocked-down to be field assembled by the

erector before installation.

6. Structural Sub-systems

6.1 Roof Extensions

6.1.1 Sidewall roof extensions extend beyond the defined building width and are generally a continuation of the main building roof slope.

6.1.2 End wall roof extensions extend beyond the defined building length and are constructed by extending the end bay purlins and eave struts of the main building past the endwall rafters.

6.1.3 Standard widths for roof extensions range from 900 mm to 1500 mm. Wider roof extensions can be used but may require heavier or additional framing.

6.1.4 Soffit panels for roof extensions are optional.

6.1.5 Main building eave gutters are normally relocated to the edge of the roof extensions. Gutter drainage is achieved by downspouts located at the building

sidewalls.6.2 Canopies

6.2.1 Sidewall canopies are cantilevered rafters attached to the sidewall columns at any point below the eave and support 200 mm deep by-pass

“Z” purlins supporting the canopy roof panels.

6.2.2 End wall canopies are cantilevered rafters along a uniform elevation attached to the end wall posts below the roof line and support by-passed 200 mm deep “Z” purlins supporting the canopy roof panels.

6.2.3 Optional canopy soffits conceal only the canopy purlins, leaving rafters exposed, unless otherwise specified.

6.2.4 Unless otherwise specified, the roof panels of the canopies shall match the color and profile of the main building roof panels.

6.2.5 The width of a canopy depends on the size of the sidewall columns or end wall posts supporting it. Practical widths range from 1500 mm to 3000 mm. Wider canopies are possible but require heavier sidewall columns or end wall posts.

6.2.6 The length of a canopy is ideally a multiple of bay lengths of the sidewalls or a multiple of column

spacings of the end walls.

6.3 Fascias and Parapets

6.3.1 Vertical fascias consist of 200 mm deep vertical posts supported by brackets from sidewall columns or

endwall posts. Cold-formed 200 mm deep “C” section top and bottom girts are flush-framed to the

vertical fascia posts. An intermediate “C” girt positioned vertically is supplied to support a valley

gutter, when required.

Standard vertical fascias project 600 mm from the building sidewall or end wall steel lines. Projections exceeding 600 mm are possible but may require heavier sidewall columns and end wall posts. The height of the fascia varies depending on actual

requirements. Typical heights range between 1000 mm to 1600 mm.

Fascia sheeting is supplied in 0.5 mm (nominal) thick,

pre-painted panels matching the sidewalls profile. Soffit panels and back-up panels are

provided only when specified.

6.3.2 Curveline fascias are of the same type of construction as vertical fascias but are sheeted with

Pre-Engineered Buildings Standard Product Specifications 9

curved profiled panels and are available in three types:

Bottom curved fascias that have a curved panel at the bottom of the fascia only.

Top and bottom curved fascias that have a curved

panel at the top and bottom of the fascia. Center curved fascias that haave a single panel

curved at the mid height of the fascia.

6.3.3 A parapet fascia is an extension of the sidewalls and endwalls above the roof line. The wall sheeting of the building will continue to the top of the parapet.

6.3.4 Standard eave gutters and downspouts are used in buildings with sidewall vertical fascias.

Valley gutters are used in buildings having sidewall parapet fascias.

7. Foundation and Anchorage7.1.1 Foundations, tie beams and concrete floor slabs

should be designed by a licensed engineer. Zamil Steel does not provide this service.

7.1.2 The design should be based on the building column specifications stated on “Issued For Construction” anchor bolt setting Plans.

7.1.3 Anchor bolts must be set in strict accordance with Zamil Steel anchor bolt setting plans. Zamil Steel is not be responsible for incorrectly set anchor bolts.
